The October issue of Avenue is out this week and is now available to read online. In today’s New York Post, Richard Johnson previews the cover story on 740 Park resident David Koch‘s philanthropy. The controversial conservative demonstrated his considerable sense of humor when he posed for us wearing a dinosaur tie (click the cover at right to see it) in front of two dinosaur skeletons at the American Museum of Natural History, one of the institutions he favors. The issue, which I guest-edited, also features this year’s Avenue A-List (are you on it?), a previously unpublished interview with the late Lauren Bacall, and my latest Unreal Estate column, revealing how I first came to write a real estate column.
